Abstract
A liquid crystal display and method of reducing light leakage in a black mode of a liquid crystal display is provided. In the liquid crystal display, a backlight assembly generates light, and a display unit is disposed over the backlight assembly to display an image by using light received from the backlight assembly. A DBEF (dual brightness enhanced film) is attached to a lower polarization plate provided at the display unit. A brightness control plate is interposed between the lower polarization plate and the DBEF to reduce the brightness of an inclined incident light that is not perpendicular to an absorbing axis of the polarization plate.
